健身瑜伽对中老年女性慢性腰痛的防治研究

为研究健身瑜伽对中老年女性慢性腰痛的防治效应,将70名中老年慢性腰痛病人分成A、B两组,C组由正常组35名无腰痛病史的中老年女性组成.对A、C进行9个月健身瑜伽训练.运用Neuromatic 2000 M/C神经肌电仪测试各组训练前后骶棘肌肌电指标,PPX-L型双能X线骨度仪测量各组训练前后骨密度值,分别进行组间比较.结果:慢性腰痛组(A、B)训练前腰背肌波幅低于正常组(P<0.01)时程大于正常组(P<0.01),训练之后腰痛组(A)和正常组(C)波幅都得到提高(P<0.01和P<0.05)时程都降低(P<0.01和P<0.05).疗效评定得出慢性腰痛治愈显效率达82.86%.结论:健身瑜伽对中老年女性慢性腰痛具有较好的防治作用.

Interweaving a mindfully somatic pedagogy into an early childhood classroom

There has been considerable distress in early childhood classrooms due to a cultural bias of Cartesian dualism, which has led to the bullying and disappearance of Body in education. Efforts of bringing about shifts in pedagogical practices toward holistic, bodily views of the self must be supported and developed. However, with classrooms that are filled with less movement and play, the marginalization of Body is of major concern. Interdisciplinary educational settings may be rich in exposing potentials and challenges of a nondual pedagogy implemented in unconsciously dualistic classroom cultures. The purpose of this article is to describe the barriers to implementation of a Mindfully Somatic Pedagogy, as well as affordances to young children throughout a preschool yoga class over an academic year. This research provides a basis for understanding how a Mindfully Somatic Pedagogy can curate holistic, first-person experiences of young children’s bodily selves within a classroom. Likewise, differing expectations of Body from adults in classrooms can lead to mixed messages for children. Understanding how bodily experiences afford young children’s development and teachers responses to Body in the classroom is informative in understanding the roles a school culture can have on the relationship between child development and teacher pedagogy.

Collaborative risk method for information security management practices: A case context within Turkey

In this case study, a collaborative risk method for information security management has been analyzed considering the common problems encountered during the implementation of ISO standards in eight Turkish public organizations. This proposed risk method has been applied within different public organizations and it has been demonstrated to be effective and problem-free. The fundamental issue is that there is no legislation that regulates the information security liabilities of the public organizations in Turkey. The findings and lessons learned presented in this case provide useful insights for practitioners when implementing information security management projects in other international public sector organizations.
